Abstract (en)
[origin: EP2292935A2] The radial fan housing assembly has a boundary wall (5) which is designed such that a radial fan receiving space extends in a wall section in a nonlinear manner. The radial fan receiving space extends in another wall section in a linear manner. The radial fan receiving space is logarithmically expanded in the former wall section.
